Description

Technical Field

[0001] This utility model relates to the field of optical lens structural components, and more specifically, to lens outer pressure rings. Background Technology

[0002] With the continuous development of science and technology, more and more smart terminals are being widely used in people's daily life and work, becoming an indispensable tool for people today. People's requirements for lenses (the window for smart terminal products to connect with the outside world) are also getting higher and higher. In order to better complete the assembly of lenses, people have come up with a variety of methods such as forward assembly, reverse assembly, and snap-fit ​​assembly. For the above-mentioned types of lenses, a pressure ring structure is often used during assembly to meet the installation requirements.

[0003] Chinese Patent No. CN215240541U discloses an external pressure ring pre-tightening mechanism, the key technical features of which are: a fixed seat with a groove; a torque wrench connecting seat disposed in the fixed seat; and at least one hook claw disposed around the fixed seat; the hook claw has a protrusion, the protrusion being able to cooperate with the groove of the external pressure ring and the fixed seat to press it tightly, and is suitable for external pressure ring mounting in optomechanical structures;

[0004] The above solution addresses the operation of pressing and fixing the external pressure ring. However, since the hook is fixed with screws, the screws are prone to loosening during long-term use, causing the lens to separate from the lens barrel. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an external pressure ring for lenses.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an outer pressure ring for a lens, including a lens barrel, a lens detachably connected to the lens barrel, an outer pressure ring body detachably connected inside the lens barrel, the side of the outer pressure ring body away from the lens barrel being attached to the lens, the outer pressure ring body being disposed between the lens barrel and the lens, and the outer pressure ring body being snap-fitted to the lens.

[0007] By adopting the above technical solution, the gap between the lens and the lens barrel is for more stable fixing and limiting of both, but the end of the outer pressure ring body on the lens barrel is tightly fitted with the lens, thereby reducing the entry of external dust and water stains into the lens barrel, thus improving the service life of the lens barrel and the lens.

[0008] The present invention is further configured such that: an upper buckle block is fixedly connected to the side of the outer pressure ring body away from the lens barrel, an upper protrusion is integrally provided on the surface of the upper buckle block, an upper hook portion is integrally provided on the upper protrusion, a lower buckle block is adhesively connected to the lens, a lower protrusion is integrally provided on the surface of the lower buckle block, and a lower hook portion is integrally provided on the lower protrusion.

[0009] By adopting the above technical solution, the lens barrel and lens can be fixed at both ends through the above technical features, and the upper hook and lower hook can be matched and snapped together, which can further improve the snapping effect between the lens barrel and the lens.

[0010] The present invention is further configured such that: the upper and lower latching blocks are both semi-circular, the upper and lower protrusions surround the surfaces of the upper and lower latching blocks, and the upper and lower hooks are arranged in opposite directions.

[0011] In summary, this utility model has the following beneficial effects: by setting up the upper locking block, upper protrusion, lower locking block, and lower protrusion, the outer pressure ring body and the lens can be clamped and limited, so that the lens is installed stably and fixed. Furthermore, both the upper and lower protrusions are provided with upper and lower hooks, which can further increase the fixing effect between the upper and lower locking blocks while the upper and lower protrusions are clamped, thereby reducing the phenomenon of separation between the lens and the lens barrel.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] Please refer to the embodiments of this utility model. Figures 1 to 4The lens outer pressure ring includes a lens barrel 1, a lens 2 detachably connected to the lens barrel 1, and an outer pressure ring body 3 detachably connected inside the lens barrel 1. The side of the outer pressure ring body 3 away from the lens barrel 1 is attached to the lens 2. The outer pressure ring body 3 is positioned between the lens barrel 1 and the lens 2, and the outer pressure ring body 3 is snap-fitted to the lens 2. In this embodiment, the diameter of the lens barrel 1 is 18.5 mm, the diameter of the lens 2 is 20.2 mm, and the lens barrel 1 has multiple sets of textures to facilitate the installation of the lens barrel 1, as well as the end of the outer pressure ring body 3 (see details). Figure 3 The purpose of placing it on the lens 2 is to reduce the entry of external dust and water stains into the lens barrel 1, thereby improving the service life of the lens barrel 1 and the lens 2.

[0019] The following discloses the structural features of the specific snap-fit ​​method between the lens barrel 1 and the lens 2. Please refer to the following: Figures 2 to 4 An upper latching block 4 is fixedly connected to the side of the outer pressure ring body 3 away from the lens barrel 1. An upper protrusion 5 is integrally provided on the surface of the upper latching block 4, and an upper hook 6 is integrally provided on the upper protrusion 5. A lower latching block 7 is adhesively connected to the lens 2. A lower protrusion 8 is integrally provided on the surface of the lower latching block 7, and a lower hook 9 is integrally provided on the lower protrusion 8. In this embodiment, three sets of upper latching blocks 4 are provided along the arc surface of the outer pressure ring body 3, and two sets of lower latching blocks 7 are provided along the arc surface of the lens 2, so that the lower latching blocks 7 can better engage with the upper latching blocks 4.

[0020] The following details the structural settings of the upper latching block 4 and the lower latching block 7. Please refer to the following: Figures 2 to 4 Both the upper latching block 4 and the lower latching block 7 are semi-circular. The upper protrusion 5 and the lower protrusion 8 are both surrounding the surfaces of the upper latching block 4 and the lower latching block 7. The upper hook 6 and the lower hook 9 are arranged in opposite directions. In this embodiment, the hooking parts of the upper hook 6 and the lower hook 9 are mutually compatible. The upper protrusion 5 and the lower protrusion 8 of the upper latching block 4 and the lower latching block 7 are respectively arranged in seven sets along the center of the upper latching block 4 and the lower latching block 7, which is to facilitate the strength of the latching between the lens barrel 1 and the lens 2.

[0021] Working principle: First, the lens 2 is installed into the lens barrel 1 by the staff. At this time, the lower latching block 7, lower protrusion 8 and lower hook 9 on the lens 2 cooperate with the upper latching block 4, upper protrusion 5 and upper hook 6. This allows the upper protrusion 5 and lower protrusion 8 to be locked in place, while the upper hook 6 and lower hook 9 further enhance the fixing effect between the upper latching block 4 and lower latching block 7, thereby reducing the possibility of separation between the lens 2 and the lens barrel 1.

[0022] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
